摘　　要：为了提高投影仪投射场景的普适性,提出了一种非规则投影曲面深度感知几何校正方法。通过对耦合性理论分析提出了削弱耦合的解决方案;采用编码的彩色结构光对非规则投影曲面进行深度获取;利用反馈式求解可视化最大投影区域,使得投影校正后的图像能够在该区域显示;利用动态分层算法对非规则曲面深度信息进行分层平面的抽离,对各个分层平面解算对应的单应性矩阵,构建单应性矩阵集合对投影图像进行几何畸变消除。通过实验分析可知,将投影图像投射到非规则曲面中,能得到校正后投影图像符合观测者的正常视觉感知。In order to improve the universality perception geometric correction on the irregular of the projector projection scene, a method of depth projection surface was proposed. With the theoretical analysis of the coupling, the weaken coupling solution was proposed. The depth of the irregular projection surface could be acquired by the encoded color structured light. After that, the feedback was used to solve the maximum visual projection area, the dynamic slicing algorithm for the irregular surfaces depth information was used to pull away the stratification planes, so a corresponding homography matrix for each stratification plane was calculated and the homography matrix set was constructed to eliminate the geometric distortion of the projected image. Through the experimental analysis, it is known that the projected image is projected to the irregular surface, and the corrected projection image can be in line with the observer normal visual perception
